Multi-level Component Oriented Methodology for Service Creation

This paper presents the COSEC methodology, a component oriented methodology for service creation. Important are the different abstraction levels, targeting a wide range of users, going from software engineers to high-end users. On a low level we create reusable developer components that groups consistent fragments of UML, SDL and Java. These developer components are composed and augmented with user-interface aspects, documentation and customization parameters to form a customer component. On a higher level, these customer components are customized and composed within a customer framework, yielding in an executable service. This combination forms an answer to the challenge of organizational and technological problems in the creation of telecom services.
